Talk given on September 21 to the Bay Area R User Group. The talk walks a stochastic project SVD algrorithm through the steps from initial implementation in R to a proposed implementation using map-reduce that integrates cleanly with R via NFS export of the distributed file system. Not surprisingly, this algorithm is essentially the same as the one used by Mahout.
